  • Ensure that the node’s file name, class’s name, and node’s folder name matches the path added to packages/nodes-base/package.json.
  • Ensure the names used in the displayOptions property are names used by UI elements in the node.

# Node icon doesn't show up in the Create Node menu and the Editor UI

  • Ensure that the icon is in the same folder as the node.
  • Ensure that it's either in PNG or SVG format.
  • When the icon is referenced in the 'icon' property, ensure that it includes the logo extension (.png or .svg) and that it is preceded by the world file:. For example, file:friendGrid.png or file:friendGrid.svg.

# Node icon does not fit correctly

  • If you are using an SVG file, make sure the canvas size is square. You can find instructions to change the canvas size of an SVG file using GIMP here (opens new window).
  • If you are using a PNG file, make sure that it's 60x60 pixels.

# Node does not show up in the Create Node menu

Ensure that the node is registered in the packages/nodes-base/package.json file.

# Changes to the description properties do not show in the UI on refreshing
